Embodiment Construction

[0038] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0039] Such as figure 1 As shown, the present invention is a wind pressure anemometer with high environmental tolerance, including a flow guide assembly and a wind pressure detection assembly. The flow guide assembly includes an upper drainage surface 1 and a lower drainage surface 2 parallel to each other. The air duct cavity 3;

[0040] The wind pressure detection assembly includes a closed cavity 6, the closed cavity 6 is located at the center of the lower drainage surface 2, the upper part of the closed cavity 6 is spherical, and the spherical surface of the closed cavity 6 is made of soft film. The circular bottom of the closed chamber 6 is provided wit...

Abstract

The invention relates to a low-wind-resistance anemometer. The low-wind-resistance anemometer comprises a flow guide assembly, a wind pressure detection assembly and a pressure stabilizing assembly. The flow guide assembly comprises an air channel cavity composed of an upper flow guide surface and a lower flow guide surface which are parallel to each other. The wind pressure detection assembly comprises a closed cavity. The closed cavity is located at the center of the lower flow guide surface. The upper portion of the closed cavity is spherical. The spherical surface of the closed cavity is made of a soft thin film. The round bottom of the closed cavity is provided with a pressure sensor. A plurality of wind deflectors are arranged between the upper flow guide surface and the lower flow guide surface in an annular array mode. The axes of the wind deflectors are located in the diameter direction of the closed cavity. The planes where the wind deflectors are located are perpendicular to a pressure borne surface. A plurality of stand columns are arranged between the upper flow guide surface and the lower flow guide surface. The stand columns are arranged around the closed cavity. An annular trapezoidal filter screen is arranged between the edge of the upper flow guide surface and the edge of the lower flow guide surface.

Description

technical field [0001] The invention relates to a low wind resistance anemometer, which belongs to the field of meteorology. Background technique [0002] In a wind power generation system, an anemometer is a weight monitoring device that senses wind force, and it is an important tool for realizing the normal operation of wind power generation equipment; currently used wind farm anemometers have a relatively high failure rate. [0003] The main reasons include: [0004] 1. Thunderstorms cause damage to the wind vane and anemometer; [0005] 2. The wind measuring equipment has been operated in the supermarket environment for a long time, and the service life is shortened; [0006] 3. The wiring is not tightly bound, and the windy weather causes the wiring to be interrupted; [0007] 4. The protection level of the anemometer is not high, and the anti-fouling ability of the sealing ring is poor. It will enter into a car and cause failure, or even lock the wind speed sensor; ...
